Export to text exports more than what is in the shopping list

If I add a recipe to the shopping list but only select that 3 ingredients need to be purchased. Then the three ingredients will be in the list. But if I then choose to export the list to text, all ingredients from the recipe will be in the list.

Example:

Have a recipe where I chose to put lemon fish and breadcrumbs on the list.

Exports to text and gets:

Purchasing

To buy:

1 pc grated cheese

1 pc onion

150 g butter

1 pc salt & pepper

1 slice of lemon

½ dl breadcrumbs

700 g white fish

This shopping list is taken from the SmakShare recipe app by Jonas Björk.

Is this how it is supposed to work?
